Case Discussion

An inguinal hernia containing an appendix is termed an Amyand hernia after Sir Claudius Amyand, who performed the first successful appendectomy in 1735. It is very rare; an appendix is demonstrated in less than 1% of inguinal hernias. The appendix is inflamed in a small percentage of Amyand hernias.
